Kapil Sharma, the host and producer of the show revealed that Ajay, who looks the most serious among the Bollywood actors is infact one of the biggest pranksters in the industry. When requested to reveal one of his recent pranks, Ajay spoke how he fooled Big B.

Ajay got his hands on a sofware that could send messages from phone A to phone B from his own phone. He decided to send a message from Big B's phone to his PR, Parag Desai's (who also is Big B's PR) phone at 10 in the night asking him to meet him at 5:30 in the morning.

When Parag met Big B and showed the message he had recieved from him, the duo were confused as to how a message was sent from his phone without his knowledge. Their confusion, apparently, was cleared by Ajay himself later but Big B too wanted the sofware that Ajay used!

The Comedy Nights With Kapil episode with Ajay Devgn and Kareena Kapoor marked the 100th episode of Kapil Sharma's show. The show was extra special with the actors' presense along with Kapil's mother, who even crakced a joke or two on the show.
